This clip introduces the 2006 expedition to remote Kamchatka, Russia. Twenty scientists arrive via helicopter to study the unique microbiology and geochemistry of the hot springs of the Uzon Caldera. Microorganisms that can survive the scalding temperatures and acidity in the springs are called extremophiles, and understanding these organisms helps answer questions about the origin and evolution of life on earth.
